It's just like paper files.

Most people who don't have time to waste post the latest document on
top.

Those who have nothing better to do with their time open the fastener,
take out all the documents, put the latest on the bottom and then
replace all the previous ones so that everything is in sequence. It
keeps them happy and occupied!

Dave,

Most everyone else top-posts. If you are reading a top-posted thread, you
open a message, read the top few lines, then move to the next message, no
scrolling to the bottom required.

Much more convenient...

Thank you for that well thought out informative response to my post.

That's fine - a lot of us won't see it anyway.

Do you see what has happened here?

Simplifying somewhat, the structure is something like:

Comment 2

Original text

Comment 1

Yuck!

It is clearly preferable to maintain a *consistent* pattern, either
*always* placing new text before old ("top-posting"), or *always*
placing new text after old ("bottom-posting").

For *very good* historical reasons, the convention on Usenet is to
place new text *after* the old text on which you are commenting,
snipping out *surplus* old text and, when commenting on a number of
fragments, placing each comment immediately after the relevant bit
of the old text.

This way, reading an article from top to bottom should make sense
in a question-and-answer kind of way. Readers who are sufficiently
familiar with the thread can skip over the quoted text, but it will
generally be available for reference simply by looking a little way
up the screen, rather as one sometimes looks back at the previous
paragraph in a book.

*One* of the reasons for quoting and commenting in this way is that
Usenet articles are *not* guaranteed to arrive at a newsserver in
the "correct" order - heck, they are not *guaranteed* to arrive at
all - and propagation delays can be quite substantial: Google take
their time even now, and once upon a time delays measured in *days*
were common.

In the early days of Usenet, *slow* and *expensive* net connections
were very common, which made snipping out excess quoted material a
Very Good Thing. Things aren't *as bad* these days, but some users
are still on slowish connections where extra bytes cost extra bucks,
so good snippage is still very good practice.

Usenet and email are two *very* different media: Usenet is a form of
*broadcast* medium where readers often find themselves dealing with
fragments of *many* threads at once; email is basically a one-to-one
medium (yes, spammers abuse it as a broadcast medium) in which you
can be far more certain that your correspondent is already familiar
with the topic of your reply, so that *appending* the previous text
for reference makes more sense. That said, interleaving old and new
text in email responses can be very useful - particularly where the
discussion *is* a series of questions and answers.

This is a bit longer than I had anticipated, but I hope you can now
see why "bottom-posting" is conventional on Usenet.
